Hello All,We have designed a custom board with STM32F777IITx MCU on it, where i am using ST Micro's CubeMX with Atollic True Studio for developing the code.Now I am also using a USB host peripheral and reading data from USB device now this data read ...
Hello,I'm trying to get LwIP working on a STM32F769I-DISC1 board but with the SBSFU bootloader.I started out with a basic project, generated with CubeMx, that sends UDP packets every 500ms (no operating system, just LwIP Raw API). This works, the boa...
Hi all!,In the case of a commercial device, who need periodic firmaware updates, is there a way to protect those updates in order to avoid for being copied and cloned?Someone can point me to a read about it?
Porting NUCLEO-H753ZI/Applications/1_Image to STM32H753.This is running on STM32H753I-EVAL2 board.The bootload can be done in 2 steps (download SBSFU.bin, then download UserApp.bin) or in 1 step (download SBSFU_UserApp.bin). The behavior is the same:...
Hi, I am coding on the NUCLEO H753ZI board with the pack for embedded cryptography (x-cube-cryptolib-3.1.2). While this folder provides example with hardcoded keys, it does not provide an example with keys imported from a file. Typically, I would lik...
Hello togetherI use the following library to create random numbers:- LibraryThe sample project runs on my NUCLEO-144 H743ZI. The problem is that the same byte array (RandomString) is generated at every time. *****************************************...
In the code below I have AES GCM correctly decrypting data using the Cryptolib. I am trying to decrypt the same data using the HAL_CRYP_AES_XXXX functions and it isn't working.Key is 32 bytes. iv is 12 bytes. header data (aad) is 3 bytes. message...
Hello All,We have designed a Custom Board with STM32F777 MCU chip and are using Atollic Truestudio with ST Micro's CubeMX for development.I have implemented a USB boot loader for the same hardware which is working fine with the Custom Board.Now i wan...
Hi,I requested a download access to X-CUBE-SBSFU firmware about two weeks ago but I didn't get a reply yet. Is there something else I should do ?
